Why does Instruction Error occur and how to resolve it?

1948396491 — Fri, 12 Mar 2021 01:34:44 GMT

Hello, the chip I use is JN5169, and the routine uses JN-AN-1217-ZigBee-3-0-Base-Device.The SDK version is 1840.

The problem I encountered was that after the reset of my software, I could not recover after receiving instruction error. After a while, the watchdog reset, and then receiving instruction error again.

I would like to ask three questions:

First: Why do you have the problem of instruction error?

Second: how to find and solve the problem?

Third, how to analyze the address information of STACK DUMP printed by the software after an exception occurs and what are the meanings of those variables in front of it?

Hi @1948396491,

I tested by my side the same example and it works. Please see the image attached.

However, could you please erase the EEPROM contents?

Please let me know your findings.
